North Dakota Subscriber Answer: Modifier 57 (Decision for surgery) doesn't usually apply to FP situations. When a physician performs an E/M in which he makes the decision for same-day surgery, you append modifier 57 to the E/M code (such as 99311-99313, Subsequent nursing facility care, per day, for the evaluation and management of a new or established patient ...).
Many insurers follow Medicare's policy and expect modifier 57 only on claims containing major surgeries. So if an FP performs only minor surgeries - those containing less than 90-day global periods - you wouldn't have a reason to use modifier 57.
In fact, Medicare's list of the top-50 FP-performed codes contains only one procedure that has more than zero global days. But even 17000 (Destruction [e.g., laser surgery, electrosurgery, cryosurgery, chemosurgery, surgical curettement], all benign or premalignant lesions [e.g., actinic keratoses] other than skin tags or cutaneous vascular proliferative lesions; first lesion) is ineligible for modifier 57 because the code has a 10-day, not a 90-day, global period. - Answers to You Be the Coder and Reader Questions provided by Barbara J.
